It was later revealed by the TDSB that Perry did not pass a swim test before going on the trip.

The board said that 15 of the 32 children on the trip had failed their swim tests.

Perry's death prompted the TDSB to introduce new rules for field trips, including mandatory second swim tests at the site of the trip. The results of those swim tests will also be seen by more people to verify the results.

Investigators have charged a teacher at the school, Nicholas Mills, with criminal negligence causing death. He remains on home assignment, said John Malloy, the TDSB's director of education.
